Every gamer has an achievement/trophy that he or she is particularly proud of. After pulling off a difficult technique or hunting down that last collectible there’s a certain satisfaction to seeing a notification that confirms your hard work was recorded for the world to see. But have you ever wondered which trophies are the most rare, across all the games out there?

PSNProfiles.com, a third-party site that imports data from PSN accounts, has a list of every trophy they track, sortable by rarity. PSNProfiles doesn’t have every PSN username in its database, so the figures may not be 100% accurate, but with more than 800,000 tracked profiles it has a decent sample size to work with. Scanning through the 25 rarest trophies provides an interesting look at what makes certain accolades more uncommon than others.

(Note: PSNProfiles calculates rarity as number of players who earned a trophy/total players for that game. Unearned trophies are excluded, which is why there aren’t more gold and platinum ones in the top 25.)

Nearly half the entries on the list are from pinball games (like Zen Pinball 1&2 and The Pinball Arcade), and almost all of those are silver-level. So in terms of rarity, it helps that pinball is a niche genre without a lot of players, but enough pinball fans are getting bronze trophies in those games seems to keep them out of the top 25. Almost all of DC Universe Online’s seven trophies on the list are bronze, however, no doubt because it’s free-to-play status means that many gamers try it but quit before getting very far.

Tougher gold trophies appear on the list for Fight Night Champions, Burn Zombie Burn, and Blacklight: Tango Down — all well known titles, but not wildly popular. Only three hard-won platinum trophies show up in the top 25, for Major League Baseball 2k10, Time Crisis, and (once again) Fight Night Champions.

So what should developers take away from this list? Pinball games are probably too hard, don’t make a trophy that you only get if you earn all the other trophies, and don’t sign up for the sequel to DC Universe Online.
